Tight junctions prevent the movement of the extracellular matrix between cells.

A) True
B) False

Which one is it please :)

To determine whether tight junctions prevent the movement of the extracellular matrix between cells, we need to understand what tight junctions are and their function.

Tight junctions are specialized structures that form a barrier between adjacent cells. They are found in epithelial and endothelial tissues, such as the linings of the digestive tract and blood vessels. The main function of tight junctions is to seal the gaps between cells, preventing the passage of substances between the cells and ensuring the integrity and polarity of the tissue.

Given this information, we can now answer the question:

B) False. Tight junctions primarily function to seal adjacent cells together, but they do not prevent the movement of the extracellular matrix between cells. The extracellular matrix is a complex network of proteins and carbohydrates that provides structural support and regulates cell behavior. It surrounds cells and fills the spaces between them but is not hindered by tight junctions.

Therefore, tight junctions do not prevent the movement of the extracellular matrix between cells.
